OK i have a couple of questions #1 I recently screwed with my timing belt an messed up the timing after destroying the distributor (screw came out of rotor) my question is i have the crank turned one tooth (clockwise) towards the fire wall an the distributor the same it runs fine but has no power do i need to move the crank another tooth clockwise or do i need to go counterclockwise ? #2 also when i first start my car in the morning it takes a little cranking to get it to fire is that due to the timing ? Also once it starts it sounds like its running out of fuel sputtering when i give it gas but once it starts warming up it stops sputtering when i step on the gas its carburated by the way if anyone can help me i would much appreciate it

An engine's distributor doesn't really care where the camshaft is as both valves are closed at firing time. It's the 2:1 ratio that's needed to drive the distributor, but really its relationship is with the block's crank and pistons. It's a matter of convenience and compromise. So we set the valve timing by timing belt and then trust that the distributor is within its range before setting. Bingo, the distributor is dynamically synced with the crank. In your case, it appears you've lost faith in the distributor's range(provided by cam), so the cam belt gets readjusted bringing new timings options to the distributor and valves. Unless you've confirmed the ignition timing requires a cam misalignment, it's recommended to reset your belt then find a suitable distributor setting within its factory range before a progressive diagnosis.

reset cam timing to correct marks, then worry about getting the distributor right, crank keyway up (or crank timing belt pulley timing mark at 6 o clock in line with mark on engine, hole in cam pulley in line with mark on top cover with all slack removed from long side of belt. Double check is tdc mark on main crank pulley, line on camshaft aligns with cast line on bearing at cam pulley end (under rocker cover) once cam timing is set, install distributor with timing set mid way on adjustment range, make sure correct firing order, and car should start. then set timing using timing light on crank pulley.

well i think i solved my starting issue i adjusted the crank another tooth to the right counterclockwise an it went crank crank vroom now i need to rebuild the carb with the car off i can push the throttle lever side to side an it will piss fuel into the carb cant blame it it has 194k miles on the original carb an its never ben rebuilt so i think its time O an does anyone know who came up with piston being tdc when timing marks are aligned that ain't nowhere near true with my car

thats a standard across the whole industry, #1 piston at TDC on compression is where "most" engines are set for cam timing. If yours isn't, i'd be looking at fractured keys, or something screwed up somewhere. How far off is it? Mines correct, 0 degree mark on crank pulley and the cast line on the cam lines up perfectly. remember the 0 degree mark may not be the same as the crank pulley keyway.

the crank timing mark is 2 teeth to the right if i go on timing marks it coughs an sputters but wont start if i go 1 tooth to the right i have to crank an crank to get it to start an once it does i have low power an it sputters like hell till it warms up with the belt 2 teeth to the right it cranks an fires but i am at the limit of my distributor an have low power i mean low enough power i can floor the pedal while driving an the engine screams at me to shift up when I'm doing 7-10 miles per hour what else can or should i do ? I need the car working properly for job hunting I'm tired of taking the buss

Have you checked the crankshaft key way yet? If the pulley bolt isn't tight enough the key gets sheered off and it severely messes with the timing. I've seen this happen on other make and models as well.

the crank timing gear key slot should b inline with the crank pulley key right ?

**Justy4x4**, that was what I was thinking as well. Perhaps a damaged timing gear. The timing belt would have to come off to inspect this. **nathan1**, please recheck your physical timing marks. Then, with the ECU in "test mode" (green connectors together), and the engine warmed up, set your idle timing. I will add some quick pics and tips on this. Top timing mark, Bottom timing mark(s) ****************************************************** ****************************************************** Things to look for **this is the damage I found after my crank pulley came loose during a three hour drive**Cracked the crank pulley from the key-way out. or CLACK CLACK CLACK as I first noticed, getting off the freeway.
Look for stretched key-way on the timing sprocket as well. any damage must be replaced. look for damaged woodruff keys, replace them anyway (0.70$ @ ACE hardware) Last tip: When re-assembling, Torque the crank pulley to 72ft-lbs (my book had it as 58~72ft-lbs, I strongly suggest the higher torque). -thanks for letting me share some horror -RRJ

OK next question is does the timing gear just slide off the crank ? an if it is stretched where would i get a new gear ? an RedRooJusty on my crank timing mark it is 2 teeth to the right

Where to find a new one (if you find damage)? My Subaru Steal-ership here would have to order it (very pricey as well). Rockauto.com might have it. To replace the damaged timing gear (in my pictures) I took a chance and salvaged a good one from my local pick-lot for 3$. -RRJ

OK got the timing gear off key way wasn't stretched so i put a little oil on it so it would slide back on an reset the timing to the marks reassembled the car an it started but i had no throttle response so i took it back apart an an advanced the crank one tooth an it fired up so i took it down the driveway an back an it has balls again just need to fill it up an take it for a road test to see if it still has balls

well did a road test an it accelerates up to 45-50 but above that i have to put my foot through the floor to gain speed what next ?

low fuel level in carb?
symptoms please...coughing? surging? flat? hissing sound with all the rubbish thats been happening to it, you could have clogged the cat converter and that will definately slow it up

I'm getting plenty of exhaust pressure out the tail pipe an as for the cat being plugged i don't know i removed the front cat honey comb a year ago when i replaced the clutch cuz it was shot full of 1/2 inch burn holes but now i have a new problem it will only crank for a couple of seconds when i hit the key then it sounds like the starter Bendix retracts an continues spinning i have an appointment with a mechanic tomorrow maybe they can tell me whats going on

well mechanic confirmed i redid my timing right but also told me y I'm not getting full power they did a compression test an i have a bad valve 2 of them are holding 120+psi an the other is holding 55 psi that would explain y my car has no balls an y i used a 1/2 tank of gas going 50 miles
